The 12 volt dynamo's are 12mm longer than the 6 volt. The difference is the backing plates. The 6 volt ones were domed, whereas the 12 volt ones flatter. There could be other issues, but suspect the plate is the problem. Peter Good www.volksgoods.co.uk

The 12v dynamos are 105mm in diameter and fit to same cover plates as 105mm 6v units. The exception to this is the 69-73 Type 2 12v generators which were longer than the Type 1 12v units, and were fitted with different cover plates to bring it back into line. My question is: where did this generator come from and was it pulled from a vehicle complete? It sounds like it is the long Type 2 generator mis-matched to cover plates for the short version.
